Doors to automatically close in event of fire. Curtains are to be assembled of in- terlocking slats cold roll formed from (galvanized steel) (stainless steel). Gauge of steel is to satisfy Under- writers' Laboratories requirement for label designated. Each end of every slat is to be fitted with a malleable iron endlock to act as a wearing surface in guides, to prevent flame passage, and to maintain slat align- ment. Steel slats are to be galvan- ized with a zinc coating in accor- dance with A.S.T.M. A 525-80. Each curtain is to be reinforced with a bottom bar consiting of two (steel) (stainless steel) angles. Spring counterbalance is to be housed in a steel pipe of diameter and wall thickness to restrict max- imum deflection to .03" per foot of door width. Springs to be helical torsion type designed to include an overload factor of 25% and for optimum ease of operation. Hand chain pull load is not to exceed 35 lbs. Springs are to be grease packed and are to be mounted on a cold rolled steel inner shaft. Spring tension is to be adjustable from outside of end bracket plate. Furnish sealed ball bearings to minimize wear of pipe shaft rotation around inner shaft. Bracket plates carrying pipe counterbalancing shaft are to be of steel plate no less than '/4" thickness. The drive end bracket plate is to be fitted with a sealed ball bearing.. Plates are to house ends of each door coil. Each door is to be equipped with an oscillating governor to control the speed of descent. Guides are to consist of (structural steel) (stainless steel) angles of 3/16" minimum thickness. Hoods to house each coil are to be fabricated of (galvanized steel) (stain- less steel) sheet metal no lighter than #24 U.S. gauge and are to be laterally reinforced. In order to pre- vent sag, furnish intermediate hood supports where door width exceeds 12'011. Locking chain hoist doors are to include a hand chain locking bracket for padlocking chain. Crank hoist doors to include a locking disc on crankbox for padlocking. Gearing for motor operated doors is to be self locking. Fimsh for ungalvanized surfaces is to consist of a shop coat of rust inhib- iting metallic primer. Field painting is not included in this section. Stainless steel to have (#2B) (#4) finish. Installation is to be by manufacturer or his authorized representative. optional featurs-5 Motor operation (add ). Motor operator is to include high starting torque motor, reduction gear- ing, solenoid brake, limit switches for upper and lower limits of door travel, emergency hand chain with elec- trical interlock to break motor c;rcuit when hand chain is engaged, mag- netic relay contactor, overload pro- tection, prewiring to terminal block, and 3 button operating station. Motor is to be removable for repair without effecting emergency opera- tion. Manufacturer is to furnish wiring diagram. Safety edge (add). Safety edges are to be furnished for motor oper- ated doors. Upon contact with obstruction door is to (stop) (stop and reverse to open position). Field wiring is not included in this section.
